Nice overview Jef. I just picked up the 1k and didn’t realize that these were essentially the glass stones.
I actually thought they were a new soaking stone but I am still happy as the 1k is probably my most used of the glass stones and it was only 35 bucks.
When the Shapton Glass stones were introduced I came across an interview with one of the Shapton sales reps who said they were designed for A2 tool steel. That seems the origin "tool steel" myth, propagated by people who didn't understand that A2 is a relatively easy steel to grind. I too would agree the Shapton Glass stones are optimized for steels with A2 levels of grindability. (Also, thanks for taking one for the team here with the Rockstar stones.)
So one thing I'll add here: Resin-bonded stones are notorious for warping. This is surely the reason why Shapton used the glass backing plate on the "Glass" series of stones. It wasn't simply to save money on abrasives. It is going to be very interesting to see how many people experience warping problems with the full-thickness stones. I'd be willing to bet most people are going to wind up gluing them down to a rigid base even before they get them down to the 5mm thickness of the Glass stones.
You always come with the info! Thanks for sharing that. Makes total sense.
@@Jef And likewise, you are one of the few people I have found who can sensibly describe sharpening stones.
The Glass stones seem to marketed more strongly towards woodworkers than the Pro stones, for chisels and plane blades etc. I think that's another reason you hear the whole "tool steel" thing. I'm slightly into woodworking and I've noticed a lot of guys using the Glass but almost never the Pros 🤷♂️ I like the Pros more myself, although the Glass 500 is a very nice stone
knife bros don't understand much. You have guys like burrfection that influence thousands of these idiots that hardness like HRC is what makes steel easy to grind or not. Which is nonsense. Some 10v at 50 HRC will be much much harder to grind than any basic carbon steel, another terms folks use without knowing what it means, it means no alloying elements okay, d2 aint carbon steel cuz it aint stainless, carbon steel means iron and carbon, no not low alloy like 52100 either, that has chromium in it, thats called low alloy, anyway, basic carbon steel like say white steel at 65 rc is much easier to grind than 10v at 45 hrc. Why? cuz of what it's made of. aka carbides. content as in how much carbide and quality as in what kind of carbide. Chromium carbide aka chromium steels aka standard stainless steels grind just fine on ceramic alumina but all these vanadium super steels that are all the rage in edc land does not. You need silicon carbide at the least to get a good edge or clean grinds after a certain grit. I mean a course alumina stone will grind 10v fine, but you're not going to enjoy trying to make 10v razor sharp on something like a 1k shapton or naniwa. i rant like a demon but this shit aint that hard and the amount of wrong info is legendary. Get basic facts right, especially if you're going to influence others or reprsent yourself like an expert.
@user-xf4es7eh9y Most "knife bros" understand more than you think...and "sharpening bros" are well aware of steel composition. We understand the effects of alloying elements and carbides. We certainly know what carbon steel is....
Thanks Jeff. Appreciate what you do.
Thanks for checking it out!
Good stuff man, really enjoyed the vid and first time hearing about these stones. 👍
I thought you might get around to trying these. Thanks for sharing
I didn’t even hear about em till last week. Had no idea any new stones were on the horizon 😁
Thank you for your review. I will stay with my Shapton Kuromaku stones.
Good choice! I prefer mine as well
My first time hearing about this stone..will be watching out for future videos from you comparing this with your other stones 👍
Hey Zul! They are revamped shapton glass. Nothing noteworthy imo 👍
Sending em out to a few buddies to test. If you were in the States I'd send em to you too. I'll be doing a GAW when they finally return, and ship em out to whoever wins. Will keep everyone posted ;)
@@Jef owh i see, revamped shapton glass..thanks for even considering me to test it, but im not in the states obviously😅..but the idea of a GAW kinda fun.
Really good video Jef. I wasn’t even aware of these stones. I’ll really be interested in hearing what kind of results you can get if you condition the stones first. Hopefully it will help with the higher carbide steel. Thanks for sharing brother it’s appreciated 👊🏼
Yea i didnt know about em till last week myself. They are going to perform exactly like shapton glass. Thats what these are basically. They may have changed a few things but they feel, act, and cut, just like them. As for higher carbide stuff, i find the pro stones to be better. I’ll of course do another vid or two after i condition and mess around some more. Overall, if you are familiar with the glass stones, these are exactly like them.
Enjoyed the video.
Your comments, as always, are appreciated! Thanks for checking it out!!
based on what I understand before this video these are just essentially the glass stones in 10mm form factor without a glass backing plate. Nothing special or magical that should make anyone rush to get em if you already have decent SNG vitified aka ceramic bonded alumina stones. IMO after trying everything on the market, I like the chosera stones best overall. But. the glass stones are very high quality and they have some good ones as well especially lower and higher grit. Like say the 120, 220, 320. All great. And the 6 to 16k are the finishers, any of those are great finishers. The 3k and 4k are also excellent ultra fine medium stones if you like sharpening that generates the smallest burrs or touch ups that remove the least steel. The shapton pro 220 and 320 are the most unique ones cuz unlike all the others they use silicon carbide and will cut easily high carbide and vanadium steels. I've learned to really like those stones. You cant listen to anything you hear about this stuff cuz all these things are just free range for bs and myths. glass vs pro, glass for sure does better on wider bevels with more refined scratchs like a chosera, its also obviously not quite as hard and obviously more friable than the pro, the pros are more like Naniwa Habiki stones which are great for woodworkers and such. extremely hard stones that wear slow asf and about as minimally friable as such a stone could get. the downside is using them on wide bevel knives isn't great. So. to me. overall the best is chosera. does the most uses better than others. and if you know where to get it, it's actually not expensive. Today in US you can get entire set of chosera stone in 15 mm form for about $250, for every single stone from 400 to 10k.
Other than your love for chosera, i agree with everything you said 👌
@@Jef cherrs man great video as usual
Are all the shapton pro stones made with silicon carbide? Or just the ones you mentioned (220 and 320)?
@@JefShapton pro has been good to me so far (1K, 5K) but I’ve tried a friend’s Shapton pro 220 and I didn’t like it.
Very interested in these. I just ordered the 500. Considering getting the 4k, and also the 1k/2k or shapton pro 1.5k/2k. Difficult to pick a 1k stone between the Shapton glass/rockstar 1k/2k and Shapton pro 1.5k/2k. Many describe the glass as having poor feedback. Im mostly sharpening softer stainless and hard AEBL. I have vitrified diamonds for hard wearing steels (which i dont currently own 😅). Do these load up more than the shapton pro?
Might have to flip a coin to break the tie!
Lookin good, Jooly! Have you been moisturizing your hands? You could be a hand model!
I got a face for radio and a voice for blogs 😂
Yeah i read that the shapton rockstar is made of the exact same composition of the shapton glass, same binder, all of it. I like the kuromaku better than the glass personally.
Ditto
Dang. If you have the glass series, would you buy the rockstar? (I don’t have an entire collection of stones but just asking). Question goes out to anyone who reads this.
I'm a huge Shapton fan and I haven't heard of these yet. They do look very similar to the Glass stones. How much were they and where did you get them if you don't mind me asking?
I had to pay for shipping from Japan. It was 37,000 yen. Basically came out to $256. Got em from miura knives.
I think you have to condition them on silicon carbide powder to open the poors of the stone maybe they do better then
Yup. I usually do but it was late at night and i didn’t want to disturb my neighbors.
The Glass stones definitely benefit from conditioning but the effect doesn't last for very long at all. You need to condition them every five minutes or so but at this point you're going to wear away the stone at an alarming rate.
Hey Jeff the rockstar is here😂
Thanks you bro
🤘
Probably gonna do a give away for these stones. I already have a set of glass stones so kinda superfulous to have them. Will keep everyone updated in next few weeks if i do
@@Jef🙋♂️😅
Any chance they had a sealant on top of that first stone?
Most stones have a “skin” on the top layer, when you purchase them. I’ve no idea what it is, but with use, it abraides away. Or you can just lap it. I did neither. I went fresh out the box, and straight to steel.
@Jef Yeah, I've had suehiro stones that actually cut even though I was through that skin yet. I'm too impatient to lap stones out of the box lol
What a shame was hoping they changed something besides the thickness.
Who knows? Perhaps they did. One of the reasons they never released larger versions of the glass stones, was due to warping. Perhaps they reformulated these, to prevent that? Time will tell. From my own experience though, that’s all they are. Repackaged, thicker, glass stones.
i can tell you didnt lap them from new. the reason the water beads like that is the coating they come with new. If you don't want that, just lap them before first use and they wont do that. Shapton says you should not use soap. but they say a LOT of bs that ain't true so who knows. also CKTG is selling these in the US.
Yea they didn’t have them when i ordered these. I looked there first and read a bit on thier forums about the stones. Mostly conjecture and what they may end up being good at etc.
